Bigfoot may have eluded the leader of a Sasquatch hunting expedition along the Buffalo National River — but the federal government didn't.

The National Parks Service said it cited the leader of the Bigfoot Field Researchers Organization for not having a permit when he took 31 Sasquatch seekers to sites along the Buffalo National River last month.

The parks service said any expedition that charges a fee requires a permit from the federal government. Expedition leader Matt Pruitt says participants paid $300 to $500 apiece to participate in the hunt.

Rangers cited Pruitt for engaging in a business without a permit or written agreement and he was fined $525.

Pruitt told the Arkansas Democrat-Gazette it was an innocent mistake and that he paid his fine last week.
